如何使用柑橘ftp组件执行sftp子命令

Question

这是我的代码，该代码登录sftp服务器并执行命令“ dzdo su-jhon”命令，并更改文件夹的路径并在该特定用户内执行ls命令。这段代码在john用户内部执行了如何使用citrus测试用例xml实现命令。

public class Sudo{
  public static void main(String[] arg) throws Exception{

  int port=22;
  String name ="john";
  String ip ="xxxx";
  String password ="root";

  JSch jsch = new JSch();
  Session session = jsch.getSession(name, ip, 22);
  session.setPassword(password);
  session.setConfig("StrictHostKeyChecking", "no");
  System.out.println("Establishing Connection...");
  session.connect();
  System.out.println("Connection established.");

  ChannelExec channelExec = (ChannelExec)session.openChannel("exec");
 channelExec.connect();
  InputStream in = channelExec.getInputStream();


  channelExec.setCommand("dzdo su - john");// changing the user 
  OutputStream out = channelExec.getOutputStream();
  out.write(("cd /xx.yy/zz \n").getBytes());// executing commands inside user

  out.write(("ls \n").getBytes());
  out.flush();


  BufferedReader reader = new BufferedReader(new InputStreamReader(in));
  String line;
  int index = 0;
  StringBuilder sb = new StringBuilder();
  while ((line = reader.readLine()) != null)
  {
      System.out.println(line);
  }
  session.disconnect();
  }
}
